Put the hitch and trailer plug on and thought I would share my trick to doing the job for those that might want to do this as a DYI. The instructions looked fair as I skimmed them after the fact so I am not going to do a detailed step by step.
First I did the plug, my SV base had the 7 pin plug hanging on the back of bumper with a cap. There is a hole already punched in metal behind the plastic cover where you see the factory plug on trucks. I used a drimel tool with an attachment that looks like a drill bit that is for cutting stuff like this plastic. Takes about 3 minutes if you are being careful, punch a hole from inside and then work from outside. If you don't have a dremel tool they sell a bit for a regular drill that will do similar job. The plug will pop into hole and clamp on to the plastic, the clips are not short enough to get on top of the metal but seem to hold good.
You are going to need a break over bar or more muscle than I have or impact if you are so lucky to have one handy as factory bolts are tight and you want some good torque when on the new ones.
Trick for making it easy as I think it can be:
I saw a few posts where they said they couldn't get it past the exhaust without dropping the hanger. This is not a fact, but you do have to use a good approach and this will help if you are doing this alone. After removing the tow hooks from the frame use a ratchet strap strung across the frame member to bumper and let it hang on either side. Lay your hitch under the back of truck on the box it came in and hook ratchet strap inside and under the hitch and hook in hole in plate that lines up with the pipe going across. Now ratchet the strap just a little so it is hanging, at this point you want to swing the exhaust side out and guide the front most part of hitch so that you can swing back into place near the hole.
Now you should be hanging roughly in place maybe a couple of more ratchets up and guide the front hole by exhaust in place for the first bolt. Turn it in by hand several turns so it won't fall out but not too far as you want plenty of slack to align all the rest of bolts. Next front on the other side and then one more back bolt each side you should be able to lift and stab them fairly easy. Now get the all the bolts started several turns, then slowly work around tightening a couple of turns. If you try to tighten one bolt all the way up you will most likely find yourself with a bolt against the edge of hitch and you could be messing up the threads a little so take you time.
Finally if doing this by hand take a break and get your torque wrench or break over bar and be sure to work your way around and get them all tight. You might want to check them after first tow.
